What should I do if the blood vessels on my hands are violent when the weather is hot?

Telangiectasia In daily life, we often see that some people's facial skin is red, and dilated capillaries can be seen by naked eyes, and some are red or purple spots, dots, lines or stars. This is telangiectasia, commonly known as red silk. It is a kind of skin injury that occurs on the face or trunk, most of which are acquired, and some patients are congenital. Facial telangiectasia is the main reason affecting beauty, which is more common in women. The clinical manifestations are filiform, punctate, star-shaped or flaky erythema on the face. If you look closely, you can see that there are many red blood vessels on the skin, just like a small red line. Many women who love beauty are often troubled by their blushing, but many people may not know that red blood will not only affect your beauty, but also affect your health and seriously affect the absorption of nutrients by the skin. Over time, it will lead to skin malnutrition, rough, dry and premature aging symptoms. In the theory of traditional Chinese medicine, it is called "blushing", which is attributed to heat stagnation of heart meridian and poor blood circulation. Blood vessels cover all organs of the body and are divided into arteries, veins and capillaries. Small arteries, veins and capillaries are distributed in skin and mucosa. Capillary dilatation refers to the filamentous, stellate or cobweb changes of these blood vessels on the surface of skin or mucosa. It is bright red, the color of the glass sheet does not fade after being pressed, and it is single or multiple, which develops slowly or does not increase obviously after it occurs. It can be limited to a certain part or a large range, it can be a local change, or it can be a special manifestation of some diseases. Most of them can't fade by themselves, and the benign process affects the appearance. Telangiectasia can be primary, such as vascular nevus and hereditary benign telangiectasia. It may also be secondary to diseases such as scleroderma and rosacea.
